Comparing very quickly my TeXLive-2007 setup, where your minimal  
example works, and my gwTeX seup, where it exhibits the same  
bahaviour as for you::

- In TeXLive, updmap.cfg (in texmf-config) contains apparently one  
single LM-related line:

Map lm.map

corresponding to lm.map which says:

% This is the global map file for the LM fonts. It includes all standard
% maps except those meant for the replacement of CM, CS, PL and VN  

- In gwTeX, updmap.cfg (in texmf.local) contains several LM-related  

Map lm.map
Map lm-ec.map
Map lm-qx.map
Map lm-texnansi.map
Map lm-ts1.map
Map lm-t5.map

It seems the interaction of the last 5, apparently superfluous, lines  
with the first line create the problem.

I'm not sure where those superfluous lines come from: a  
misconfiguration of gwTeX as shipped, or a remnant of a previous  
installation of gwTeX which hasn't been erased by a more recent  
installation (given, I think, /usr/local/gwTeX/texmf.local/web2c/ 
updmap.cfg is essentially left unchanged by a new install). Since / 
usr/local/gwTeX/texmf/web2c/updmap.cfg, the default gwTeW updmap.cfg,  
does not contain the superfluous 5 lines, I think the answer is the  
second: a remnant of the previous organization of the LM map files.

Whatever the cause, a possible cure is:

sudo -H updmap-sys --nohash --nomkmap --disable lm-ec.map
sudo -H updmap-sys --nohash --nomkmap --disable lm-qx.map
sudo -H updmap-sys --nohash --nomkmap --disable lm-texnansi.map
sudo -H updmap-sys --nohash --nomkmap --disable lm-ts1.map
sudo -H updmap-sys --nohash --nomkmap --disable lm-t5.map
sudo -H updmap-sys

Hope this works,
